Fins2

The design for this LED table lamp serves as an excellent test case for any 3D printer due to its intricate vertical fins. To make these thin fins stiffer, I added a small rectangular cross piece, resulting in each fin's cross-section resembling a cross. Consequently, the printer must execute 12 precise right-angle turns for every loop of each fin without compromising its position while extruding the filament. This demands exceptional precision as it approaches the top part of each fin before they join together. I employed three colors to create this print, but initially misjudged the amount of filament available on the spool for the bottom orange color. As I noticed it was running low, I switched to a fuller reel of a slightly darker orange shade. Upon reviewing the result, I decided to opt for the top yellow color, which I believe adds a pleasing finish to the overall design. A short video showcasing the lamp with a battery-powered LED on a small turntable is available at https://youtu.be/Dq9PzppQWj8. This lamp is specifically designed to accommodate any of several LED lights known as "puck" lights, which can be powered by either batteries or wall power.

Given the need for 12 right-angle corners per loop of each fin, this part required an impressive 40 hours and 45 minutes to print using a print speed of 80 mm/sec and a layer height of 0.200 mm.
